These days, Hunan TV host the big concert – Happy Girls.
Long1 and xinxin like it very much, they even use their cellphones to suppose the girl who they like most. This way is easy if you have enough money then you can make a contribution toward your lover.
But sometimes, it also causes the problem of injustice. Those who has a lot of money can support their lover in every second. So now, we make a rule to restrict them – every tel-number can just support once in one minute (i.e two messages should have difference bigger or equal 60s).
As an exerllent programer, your mission is to count every Happy girl’s result.
